CROSS-REFERENCE TO RELATED APPLICATION

This application is a Utility Patent application based on previously filed U.S. Provisional Patent Application No. 63/085,670 filed on Sep. 30, 2020, the benefit of the filing date of which is hereby claimed under 35 U.S.C. § 119(e) and the contents of which is further incorporated in entirety by reference.

TECHNICAL FIELD

The present invention relates generally to file systems, and more particularly, but not exclusively, to managing user interfaces for displaying information about a distributed file system environment.

BACKGROUND

Modern computing often requires the collection, processing, or storage of very large data sets or file systems. Accordingly, to accommodate the capacity requirements as well as other requirements, such as, high availability, redundancy, latency/access considerations, or the like, modern file systems may be very large or distributed across multiple hosts, networks, or data centers, and so on. In some cases, the size or distributed nature of a modern hyper-scale file systems may make it difficult to provide users or administrators useful performance or status information that may also be understandable, intuitive, or concise. The large number of files in modern distributed file systems may make providing user interfaces for managing distributed file systems difficult because of the resources that may be required to visit the files to determine state or other information in the file system. Thus, it is with respect to these considerations and others that the present invention has been made.

Network computer 300 may include many more or less components than those shown in FIG. 3. However, the components shown are sufficient to disclose an illustrative embodiment for practicing these innovations. Network computer 300 may represent, for example, one or more embodiments of a file system management server computer such as application server computer 116, file system management server computer 118, file system management server computer 120, or the like, of FIG. 1.

Network computers, such as, network computer 300 may include a processor 302 that may be in communication with a memory 304 via a bus 328. In some embodiments, processor 302 may be comprised of one or more hardware processors, or one or more processor cores.

Sensors may be one or more hardware sensors that collect or measure data that is external to network computer 300. Human interface components can be physically separate from network computer 300, allowing for remote input or output to network computer 300. For example, information routed as described here through human interface components such as display 350 or keyboard 352 can instead be routed through the network interface 332 to appropriate human interface components located elsewhere on the network. Human interface components include any component that allows the computer to take input from, or send output to, a human user of a computer. Accordingly, pointing devices such as mice, styluses, track balls, or the like, may communicate through pointing device interface 358 to receive user input.

Illustrative Logical System Architecture

FIG. 4 illustrates a logical architecture of system 400 for user interfaces for managing distributed file systems in accordance with one or more of the various embodiments. In one or more of the various embodiments, file systems, such as, file system 402 may be arranged to be communicatively coupled to one or more networks, such as, networks 404. Accordingly, in one or more of the various embodiments, one or more clients, such as, client computer 406 and client computer 408 may be arranged to access file system 402 over networks 404. In some embodiments, clients of file system 402 may include users, services, programs, computers, devices, or the like, that may be enabled to perform one or more file system operations, such as, creating, reading, updating, or deleting data (e.g., file system objects) that may be stored in file system 402. In some embodiments, file system 402 may comprise one or more file system management computers, such as file system management computer 410. Also, in one or more of the various embodiments, file systems, such as file system 402 may include one or more file system objects, such as file system object 412 or file system object 414. file system object 412 or file system object 414 may represent the various objects or entities that may be stored in file system 402. In some embodiments, file system objects may include, files, documents, directories, folders, change records, backups, versions, branches, or the like.

In one or more of the various embodiments, the implementation details that enable file system 402 to operate may be hidden from clients, such that they may be arranged to use file system 402 the same way they use other file systems. Accordingly, in one or more of the various embodiments, clients may be unaware that they are using a distributed file system because file system engines may be arranged to mimic the interface or behavior of standard file systems.

Also, while file system 402 is illustrated as using one file system management computer with two sets of file system objects, the innovations are not so limited. Innovations herein contemplate file systems that include one or more file system management computers or one or more file system object data stores. In some embodiments, file system object stores may be located remotely from one or more file system management computers. Also, a logical file system object store or file system may be spread across two or more cloud computing environments, storage clusters, or the like.

In one or more of the various embodiments, one or more clients may be configured to be administrators that may have roles that enable a varying degree of administrative powers to administer file system objects. In one or more of the various embodiments, administrators may be enabled to established the various rule-based policies that are enforced by one or more file system engines that may be running on the one or more file system management computers.

In one or more of the various embodiments, visualization engines may be arranged to execute on one or more file system management server computers, such as, file system management server computer 410. In one or more of the various embodiments, visualization engines may be arranged to generate and manage one or more visualizations that may represent various characteristics, statuses, activities, or the like, that may be associated with a file system. In some embodiments, visualizations may be employed in various applications, such as, administrative dashboards, monitoring applications, alerts, notification reports, or the like.

In one or more of the various embodiments, the particular visualizations displayed in an application may vary depending on the file system or its applications. Similarly, in some embodiments, the particular elements of a visualization, such as, scale, units, labels, colors, type of chart or graph, or the like, may vary depending in the file system or its application. Accordingly, in some embodiments, visualization engines may be arranged to employ rules, templates, or the like, provided via configuration information to determine which visualization to display to account for local circumstances or local requirements.

FIG. 5 illustrates a logical representation of graphical user interface 500 for user interfaces for managing distributed file systems in accordance with one or more of the various embodiments. In one or more of the various embodiments, a graphical user interface (GUI), such as, GUI 500, may be arranged to include one or more panels that may provide various features that enable user interfaces for managing distributed file systems. In some embodiments, such panels may include, various panels, such as, panel 502, panel 504, panel 506, or the like. Further, in some embodiments, one or more panels may include or be comprised of one or more other panels.

Also, in some embodiments, one or more panels may be arranged to be reactive to one or more local or remote external inputs associated with one or more file system characteristics.

FIG. 6 illustrates a logical representation of visualizations 600 for user interfaces for managing distributed file systems in accordance with one or more of the various embodiments. In one or more of the various embodiments, visualization engines may be arranged to generate a variety of visualizations for different file system metrics. In some embodiments, metrics may be real-time values, historical values, aggregate values, categorical values, or the like, or combination thereof.

In this example, for some embodiments, visualization 602 represents a visualization arranged to provide information associated with a file system characteristic or file system items, such as, number of connections, number of clients, bandwidth utilization, or the like, associated with various nodes, storage devices, partitions, or other items of a file system. However, in some embodiments, large file systems may include dozens, hundreds, thousands, or millions (or more) of various file system items. Accordingly, in some embodiments, employing a visualization that shows values for individual items may disadvantageously provide too much information. For example, for some embodiments, if a visualization shows individual activity metrics for 100s of concurrent clients of the file system it may be difficult for a user to discern actionable information from among the noise. Also, in some embodiments, a visualization that represents many instances of normal or average behavior/activity may result in a visualization that may be cluttered, noisy, or otherwise difficult for some users to interpret. Further, in some embodiments, such visualizations may require a display geometry that may restrict the visualizations to large display systems, thus precluding the use of smaller mobile devices.

Accordingly, in one or more of the various embodiments, visualization engines may be arranged to determine and display information associated with file system items or activities that may be outliers. In one or more of the various embodiments, visualization engines may be arranged to identify values for a given metric that may be at or above a defined upper percentile or at or below a defined lower percentile relative the distribution of metric values.

In this example, visualization items 608 represent visual information included for file system item metrics that may have values at or exceeding a defined upper percentile. Similarly, in this example, visualization items 610 represent visual information for file system item metrics that may have values at or below a defined lower percentile value.

In one or more of the various embodiments, the upper percentile value or lower percentile value may be determined or modified automatically based on the number items associated with the visualization. In some embodiments, rather than distribution percentiles, visualization engines may be arranged to select a number of top valued items or a number of least valued items, such as, the top three or bottom three. In some embodiments, the value of the percentiles, or the like, may vary depending on the display geometry of the visualization.

In one or more of the various embodiments, visualization engines may be arranged to exclude some or many item values from a visualization. In some embodiments, items associated with metrics having normal or average values may be excluded from a visualization. Accordingly, in some embodiments, the visual noise associated with many average or otherwise normal metric values may be eliminated from a visualization. In this example, for some embodiments, ellipsis, such as, ellipsis 612 may be included in a visualization to indicate that items below the upper percentile or above the lower percentile may be excluded from visualization 602.

Also, in one or more of the various embodiments, one or more visualizations may be provided to represent real-time system-wide or system-level values. For example, visual information representing the average number of connections per minute, or the like, may be displayed in real-time (or near real-time). In this example, for some embodiments, visualization 604 includes line graph 614 to represent a file system item metric value.

In some embodiments, visualization engines may be arranged to combine two or more visualizations to provide additional context for the represented metric values. In this example, for some embodiments, visualization 606 may be considered a combination of visualization 602 and visualization 604 where visualization 604 has been overlaid visualization 602. In some embodiments, this arrangement may provide additional context to both visualizations advantageously reducing the amount of display area required to convey the same visual information. In this example, visualization 606 displays the visual information of visualization 602 and visualization 604 in the space of one visualization.

Note, in some embodiments, visualizations may be arranged to represent various common, uncommon, or custom, visualization elements, such as, rows, columns, line plots, surface plots, bar charts, pie charts, tables, text fields, text areas, or the like. For brevity and clarity, examples included herein are necessarily limited. However, the described visualizations are at least sufficient to disclose the innovations described herein. Accordingly, one of ordinary skill in the art will appreciate that the innovations described herein anticipate many more different types of visualizations, metrics, file items, or the like, than those expressly included here.

FIG. 7 illustrates a logical schematic of visualization 700 for user interfaces for managing distributed file systems in accordance with one or more of the various embodiments. In one or more of the various embodiments, there may be so many file system objects in a file system that determining an accurate value of various metrics associated with the file system as whole may be difficult. In some embodiments, in large file system, various aggregate metrics, such as, file size, directory size, file counts, or the like, may be maintained on the fly as individual changes (e.g., writes, reads, or the like) are made to a file system. For example, as a file is written to a file system, aggregate metrics of the parent directories associated with the file may be modified to account for the new file. Accordingly, in one or more of the various embodiments, the file system may maintain accurate aggregate metrics that may be employed to generate visualizations or reports about the file system.

In one or more of the various embodiments, each parent object in the file system tree may be arranged to locally store or reference various aggregate metrics, such as, size, access count, average age, or the like. In one or more of the various embodiments, file system engines may be arranged to employ configuration information to determine the specific aggregates that may be maintained for a file system to account for local circumstances or local requirements. For example, if a user requests the amount storage taken up by a directory in the file, the value may be immediately returned to the client without have to scan the file system.

However, in one or more of the various embodiments, it may be advantageous provide one or more visualizations that illustrate changes in aggregate values overtime. However, in some embodiments, file systems may include so many file system objects in so many directories that scanning them all to determine changes in aggregate values may be disadvantageously resource intensive. In some embodiments, traversing a file system to identify changes one or more aggregate values may take so long that a scan of aggregate values of the entire file system may be effectively meaningless or impossible. For example, in some cases, conventional scans of aggregate values may take hours or days such that for active file systems the result of such long running scans may be meaningless because of changes that occurred while the scan of aggregates is occurring.

Further, in some embodiments, if a file system has thousands or millions of directories, changes to aggregate metric values associated with a single directory may be meaningless or confusing because of the sheer number of directories in the file system. Thus, in some embodiments, a conventional visualization that attempts to represent the changes to aggregate metrics for all directories in a file system may be difficult for users to interpret.

Accordingly, in one or more of the various embodiments, visualization engines may be arranged to divide the file system into metric partitions based on the total value of the aggregate metric of interest. In one or more of the various embodiments, a visualization engine may be configured to divide the file system into metric partitions based on a defined fractional value. Thus, in some embodiments, the changes to the aggregate metric may be computed for each fractional partition of the file system. In some embodiments, visualization engines may be arranged to determine a partition size threshold based on dividing the value of the aggregate metric of interest by a defined number of metric partitions. For example, in some embodiments, a visualization engine may be arranged to employ metric partitions that are based on 1/1000 of the total value of the aggregate metric. Thus, in this example, if the total storage size (storage used) by the file system is one terabyte, each metric partition would represent one gigabyte of storage because one terabit is 1000 gigabytes. Likewise, if the total size of the file system is ten terabytes, each metric partition in this example would be ten gigabytes.

In some embodiments, visualization engines may be arranged to employ configuration information to determine a metric partition fraction or count for aggregate metrics to account for local circumstances or local requirements.

In this example, panel 702 include a visualization that may be considered to be based on metric partitions as described above. In this example, there are 33 marks each representing 1/33 of the aggregate metric value represented by the visualization. Accordingly, in this example, each mark, such as, mark 706 may represent a change the values of an aggregate metric over a given time period. In this example, mark 706 indicates that for 1/33 of the file system the metric value has increased. The amount of increase represented by mark 706 may depend on the scale of panel 702. Also, in this example, line 704 may represent zero or no change. Thus, in this example mark 708 represents that the aggregate metric value has decreased.

In one or more of the various embodiments, each metric partition may correspond to a portion of the file system that has the fractional value of the total aggregate metric of the file system. For example, if the aggregate metric is file system storage size, each mark in panel 702 represents 1/33 of the total amount of data in the file system and the file system has a total 330 terabytes of data. Thus, in this example, each mark corresponds a portion of the file system that is storing 1 terabyte of data. Note, in some embodiments, the number of directories, file system objects, nodes, or the like, represented by a metric partition may vary because the size of the individual objects may vary. For example, in some embodiments, if each metric partition represents a terabyte of data, a first metric partition may correspond to a single terabyte sized object while a second metric partition may correspond to 1000 one gigabyte objects, and so on.

Further, in some embodiments, visualization engines may be arranged to employ the metric partitions size value as a threshold value that determines the precision of visualizations of changes in aggregate metrics. In one or more of the various embodiments, visualization engines may be arranged to employ the threshold value to limit the depth of traversal in the file system.

In one or more of the various embodiments, visualization engines may be arranged to generate visualizations such as visualization 700 to enable users to click through a given metric partition mark, such as, mark 706, mark 708, or the like, to instantiate another visualization or report that shows the file system objects that comprise the metric partition. Accordingly, in some embodiments, if anomalous changes may be indicated by one or more marks in a visualization like visualization 700, a user may quickly determine the underlying file system objects that may be involved by drilling down via the one or more marks that appear anomalous.

FIG. 8 illustrates a logical schematic of file system portion 800 for user interfaces for managing distributed file systems in accordance with one or more of the various embodiments. As described above, in some embodiments, visualization engines may be arranged to determine a plurality of metric partitions based on a fraction of an aggregate metric value of a file system, such as storage size, file system capacity, or the like. Here, storage size refers to the amount of data actually stored in the file system where file system capacity refers to the capacity of a file system irrespective of the data currently stored in the file system.

In one or more of the various embodiments, visualization engines may be arranged to execute one or more descent traversals of a file system tree to identify sub-trees that represent the file system objects that may be associated metric partitions. Accordingly, in some embodiments, each determined sub-tree may have a local aggregate metric value approximately equivalent to a fractional value of the aggregate metric of interest where the fraction may be determined based on defined number of metric partitions. For example, for some embodiments, if a visualization engine may be configured to generate 1000 metric partitions based on file system storage size, each metric partition may be associated with one or more file system sub-trees that have local storage size values that add up to 1/1000th of the total storage size of the file system.

In this example, for some embodiments, file system portion 800 includes some directories (e.g., parent objects) and some files (non-parent file system objects). Also, in one or more of the various embodiments, each parent object in file system portion 800 may be associated with meta-data that includes one or more aggregate metric values. And, in this example, each file object may be associated with meta-data that includes a metric value the contributes to the value of the aggregate metric value of its parent object. For example, in this example, file object 808A (File D) is associated with meta-data 808B that stores a metric value of 50 (e.g., file size). And, because in this example, file object 808A is the only child object of parent object 804A, meta-data 804B stores an aggregate metric value of 50—based on the aggregation of all the child objects underneath it. In this case, parent object 804A only has one child, so its aggregate metric value is the same as its one child.

In contrast, parent object 802A is associated with meta-data 802B that stores an aggregate metric value of 1250 representing the aggregation of the aggregate metric for all of the child objects under parent object 802A.

For this example, the aggregate metric stored in the meta-data may be assumed to be storage size in megabytes (e.g., file size) and the fractional threshold value for each metric partition may be assumed to be 1000 megabytes (one gigabyte). Accordingly, in some embodiments, visualization engines may be arranged to determine the metric partitions for a file system portion, such as, file system portion 800 by starting a descent traversal at parent object 802A. Accordingly, at parent object 802A, the visualization engine may be arranged to inspect the aggregate metric value associated with parent object 802A, which, in this example may be 1250. In this example, 1250 exceeds the maximum size of a metric partition (1000 in this example). Accordingly, the visualization engine may be arranged to continue its descent traversal of the file system.

Accordingly, in this example, the visualization engine may visit object 804A. Object 804A is associated with meta-data 804B that indicates that the aggregate size of the child objects of parent object 804A may be 50. In this example, 50 is less than the metric partition size (e.g., 1000) so the visualization engine may stop its descent because it is now known that there may be no objects below parent object 804A that would cause it exceeds the metric partition size.

In contrast, in this example, if the visualization engine visits object 806A meta-data 806B has aggregate metric value of 1200. In this example, 1200 is larger than the metric partition limit of 1000 so the descent traversal may continue. Accordingly, the visualization engine may next visit object 810A where meta-data 810B has an aggregate metric value of 200. Here, 200 is less than 1000, so the visualization engine may stop the descent traversal because now it is known that everything below object 810A has a size of 200 or less.

However, in this example, if the visualization engine visits object 812A, meta-data 812B shows its aggregate metric value is 1000. In this example, since object 812A is a leaf of the tree, the descent traversal has to stop.

Next, in this example, the visualization engine may backup to object 806A, subtracting the aggregate metric value associated with object 812A from the aggregate metric value associated with object 806A. In this case, because aggregate metric value of 812A subtracted from its parent object (object 806A) is less than the metric partition size limit, the traversal of file system portion 800 may be considered complete with two metric partitions determined. Accordingly, in this example, metric partition 814 may include object 802A, object 804A, object 808A, object 806A, and object 918E while metric partition 816 may include object 812A. Note, in this some cases, metric partition 814 may include additional upstream objects not shown in this simplified example.

Accordingly, in one or more of the various embodiments, visualization engines may be arranged to begin at the root object of a file system and perform a descent traversal until each object in the file system is associated with a metric partition. However, in some embodiments, because the metric partition size limit is also the minimum threshold that ends a descent down a tree branch many traversal steps may be eliminated.

In one or more of the various embodiments, visualization engines may be arranged to employ the metric partitions to rapidly determine changes in aggregate metrics by limiting its scan of file system objects to the roots of the sub-trees comprising the metric partitions. For example, in this example, the initial aggregate metric value for metric partition 814 may be 200. Thus, in this example, if a file having a size of 50 GB is added as a child to object 804A, metric partition 802A may aggregate metric value may be arranged to be increased by 50 GB.

Next, in one or more of the various embodiments, control may be returned to a calling process.

FIG. 10 illustrates a flowchart for process 1000 for determining a partition based visualization for user interfaces for managing distributed file systems in accordance with one or more of the various embodiments. After a start block, at block 1002, in one or more of the various embodiments, the visualization engine may be arranged to determine a storage size value that may be associated with file system. In some embodiments, visualization engines may be arranged to determine the current storage size based on information provided or maintained by the file system engine. For example, in some embodiments, the file system engine may be arranged to maintain a running count of the amount of data stored in the file system. In some embodiments, the storage size may be provided in terms of bytes, gigabytes, terabytes, or the like. In other embodiment, the storage size may be based on storage device blocks, storage devices, or the like. In some embodiments, the storage size may be based on number of objects.

Also, in one or more of the various embodiments, visualization engines to employ other file system-wide metrics values besides storage size. Accordingly, in some embodiments, visualization engines may be arranged to employ rules, instructions, or the like provided via configuration information to determine the particular metric to use as base value for partitioning the file system.

At block 1004, in one or more of the various embodiments, the visualization engine may be arranged to determine the size of metric partitions. In some embodiments, metric partitions may be sized based on fraction of the base metric. For example, in some embodiments, if a file system may be configured to have 1000 metric partitions, each partition may be sized based on 1/1000 of the base value. Thus, in some embodiments, if the base value is storage size, the partition will be sized based on a fraction of the storage size.

In some embodiments, visualization engines may be arranged to generate a fixed size of metric partitions. For example, if the number of partitions is defined to be 1000, each partition may be sized based on dividing the base value by 1000. Also, in some embodiments, visualization engines may be configured to define a maximum or minimum partition size.

At block 1006, in one or more of the various embodiments, the visualization engine may be arranged to traverse the file system to determine the metric partitions. In one or more of the various embodiments, visualization engines may be arranged to traverse the file system to determine file system objects to divide into metric partitions. Accordingly, in some embodiments, visualization engines may be arranged to identify one or more sub-trees in the file system that may be grouped into metric partitions. For example, in some embodiments, if the metric partition size may be 100 GB, one or more sub-tree in the file system up to about a size of 100 GB may be grouped into metric partitions. In some cases, for some embodiments, one or more metric partitions may be over-sized or under-sized depending on how the object in a file system may be arranged. However, in one or more of the various embodiments, every file system object in the file system may be associated with a metric partition. In some embodiments, the strategy for determining under-sized or over-sized metric partitions may vary depending on the characteristics of the file system or local circumstances or local requirements as determined via configuration information.

At block 1008, in one or more of the various embodiments, the visualization engine may be arranged to monitor one or more aggregate metrics for each metric partition. In one or more of the various embodiments, metric partitions enable visualization engines to monitor one or more aggregate metrics associated with the sub-trees that comprise the metric partitions.

At block 1010, in one or more of the various embodiments, the visualization engine may be arranged to generate a visualization based on the aggregate metric values associated with the metric partitions. In one or more of the various embodiments, metric partitions enable the generation of various visualizations that may be based on metrics associated with partitions. Accordingly, in one or more of the various embodiments, visualizations may be designed to effectively present visual information for a known number of metric partitions. For example, in some embodiments, absent metric partitions the number of sub-trees or parent objects may be practically unbounded. Accordingly, for this example, designing effective visualizations may be difficult because the number of items in the visualization may be difficult to anticipate. In contrast, in one or more of the various embodiments, if the number of metric partitions may be known to be relatively constant, effective consistent visualizations may be designed and displayed. Because, in some embodiments, even the number of objects associated with a metric partition may vary, the number of metric partitions may remain consistent.

Further, in one or more of the various embodiments, metric partitions may enable visualizations that show how metrics associated with metric partitions has changed in reasonable time period. For example, visualization engines may be arranged to rapidly update a visualization based on 1000 metric partitions rather than visualizations based on 1,000,000,000 smaller objects that each would have to be visited to determine relative changes in values.

Next, in one or more of the various embodiments, control may be returned to a calling process.

FIG. 11 illustrates a flowchart for process 1000 for associating file system objects with metric partitions for user interfaces for managing distributed file systems in accordance with one or more of the various embodiments. After a start block, at block 1102, in one or more of the various embodiments, the visualization engine may be arranged to visit the next parent object in a file system. In one or more of the various embodiments, initially, the visualization engines may be arranged to start with the root object of the file system.

In one or more of the various embodiments, visualization engines may be arranged to traverse down one or more branches of the file system. Accordingly, in one or more of the various embodiments, one or more parent objects (e.g., directory objects) may be visited during the traversals.

Accordingly, in some embodiments, visualization engines may be arranged to visit each parent object that is associated with an aggregate size value that equals or exceed the threshold value.

At decision block 1104, in one or more of the various embodiments, if the aggregate metric value associated with the visited parent object matches or exceeds the threshold value, control may flow to decision block 1106; otherwise, control may flow to block 1108.

In one or more of the various embodiments, as described above, the number of metric partitions being generated and the storage size or capacity of a file system may determine the threshold value that may determine which objects may be associated with a metric partition.

Accordingly, in one or more of the various embodiments, visualization engines may be arranged to compare the local aggregate storage size associated with the visited parent object to determine if the sub-tree under the parent object can fit with the size limit for metric partitions.

At decision block 1106, in one or more of the various embodiments, if an end of a branch in the file system may be reached, control may flow to decision block 1112; otherwise, control may loop back to block 1102.

In one or more of the various embodiments, in some cases, a traversal may reach the end of a branch in file system. Thus, in some embodiments, even though the current parent object may be associated with a local storage size that exceeds the threshold value there may be no more parent objects below it. Accordingly, in some embodiments, the visualization engine may be arranged to end the traversal of the branch.

At block 1108, in one or more of the various embodiments, the visualization engine may be arranged to end the descent of the current branch of the file system. In one or more of the various embodiments, if the visited parent object is associated with a local storage size value that may be less than the threshold value, there is no need to continue traversing down this branch of the file system because the entire sub-tree of file system below this position may fit in a metric partition. Accordingly, in one or more of the various embodiments, depending on the value of the threshold value, performance of the traversal may be improved by excluding the many objects that may be below the threshold.

In one or more of the various embodiments, visualization engines may be arranged to automatically stop the traversal of a branch of sub-tree at the visited parent object associated with a storage size that may be less than the threshold value.

At decision block 1110, in one or more of the various embodiments, if the partitioning of the file system may be finished, control may flow to block 1114; otherwise, control may loop back to block 1102. In one or more of the various embodiments, after the traversal of one sub-tree has finished there may be one or more remaining sub-trees in the file system to evaluate. Accordingly, in one or more of the various embodiments, if so, the visualization engines may be arranged to back up until to another sub-tree root (e.g., another parent object) to begin a traversal of another sub-tree.

Note, in some embodiments, one or more visualization engines (or process, threads, or the like, associated with one visualization engine) may traverse different portions of the file system in parallel or otherwise concurrently. Accordingly, one of ordinary skill in the art will appreciated that in some embodiments, more than one sub-tree of the file system may be traversed or otherwise evaluated concurrently. In some embodiments, portions of the file system may be located or managed by separate storage computers that may be employed separate visualization engines to determine one or more metric partitions by traversing one or more portions of the file system.

At decision block 1112, in one or more of the various embodiments, if the partitioning of the file system may be finished, control may flow to block 1114; otherwise, control may loop back to block 1102. This decision block may be considered similar to decision block 1112. Accordingly, in some embodiments, the visualization engine may be arranged to continue traversing other branches of the file system to determine metric partitions.

At block 1114, in one or more of the various embodiments, the visualization engines may be arranged to fix up one or more metric partitions.

In one or more of the various embodiments, visualization engines may be arranged to perform one or more actions to adjust one or more metric partitions to improve the balance of objects. In one or more of the various embodiments, the last parent object in a file system branch may be associated with storage size value that exceeds the threshold value. Accordingly, in some embodiments, the visualization engines may be arranged to evaluate the size of the child objects of such parent objects. In some embodiments, these file system objects may be files rather than directories.

Accordingly, in one or more of the various embodiments, visualization engines may be arranged to evaluate the storage size value for the individual file system objects associated with parent object to attempt to balance them into one or more metric partitions. In one or more of the various embodiments, the particular balance strategy may vary depending on the number of object or the size of objects. For example, for some embodiments, if the child objects associated with a parent object are about the same size, the visualization engines may be arranged to associate half of the object into on metric partition and the other half in another. Likewise, in some embodiments, if there are a few large objects and many small objects, the visualization engines may be arranged to associate the small objects with the larger objects in one or more metric partitions.

Also, in some embodiments, visualization engines may be arranged to employ a ‘rounding’ strategy that determines if the child objects of an over-sized branch ending parent object are divided or distributed into two or more metric partitions or all held in one over-sized metric partition. For example, for some embodiments, if the threshold value may be 10 GB, and the end branch parent object has a storage size of 12 GB, the visualization engines may be arranged to resolve the over-sized sub-tree by automatically creating an over-sized metric partition. In contrast, for example, if the storage size of the parent object of the over-sized sub tree may be 20 GB, the visualization engine may be arranged to attempt to split the parent object's child objects into more than on metric partition.

In one or more of the various embodiments, visualization engines may be arranged to employ rules, instructions, or the like, provided via configuration information to determine how over-sized or under-sized sub-trees may be fit into metric partitions.

Further, in some embodiments, visualization engines may be arranged to perform more general optimizations that may move some objects from over-filler metric partitions into under filled partitions if any.

Also, in one or more of the various embodiments, visualization engines may be arranged to perform other fix-up actions that may attempt rules that may balance metric partition membership of objects based on various criteria.

In some embodiments, visualization engines may be arranged to modify metric partition membership based on the physical location of objects such that one or more objects may be reassigned to different metric partitions to be associated with other objects on the same storage device, storage computer, cluster, or the like.

Also, in some embodiments, visualization engines may be arranged to group objects in metric partition based on usage characteristics, such as, recency, read/write average size, read/writes per time, type of application accessing or generating the objects, roles of users accessing the objects, or the like.

Also, in some embodiments, visualization engines may be arranged to adjust metric partition membership based on storage device or storage computer characteristics that store objects. Accordingly, in one or more of the various embodiments, visualization engines to employ rules, instructions, or the like, provided via configuration information to determine how to adjust or balance one or more metric partitions.

Next, in one or more of the various embodiments, control may be returned to a calling process.

FIG. 12 illustrates a flowchart for process 1200 for user interfaces for managing distributed file systems in accordance with one or more of the various embodiments. After a start block, at block 1202, in one or more of the various embodiments, a visualization engine, file system engine, or monitoring engine may be arranged to determine one or more metric values for one or more file system characteristics. In one or more of the various embodiments, metrics may be related to various activity that may be directly or indirectly associated with the file system. In one or more of the various embodiments, one or more metrics may be based on one or more aggregations or various measurements, signals, events, or the like, that may be associated with a file system. Also, in some embodiments, one or more metrics may be based real-time or near real-time measurements, signals, events, or the like.

In one or more of the various embodiments, metrics may be derived from one or more other metrics. For example, in some embodiments, a primary metric may be arranged to accumulate the number of client connections over the lifetime of the file system, while a derived metric may represent the change in connections over a specified time period.

In one or more of the various embodiments, one or more metrics may be measured directly by the file system engine, visualization engine, or monitoring engine while one or more other metrics may be measured by one or more external or third party services or processes.

At block 1204, in one or more of the various embodiments, optionally, the visualization engine may be arranged to fit the one or more metric values to a distribution curve. In one or more of the various embodiments, visualization engines may be arranged to determine a type of distribution, such as, normal distributions, or the like, that may best match the collected metrics. Accordingly, in some embodiments, visualization engines may be arranged to apply one or more goodness of fit functions to the collected metrics to determine a distribution that best fits the collected metrics. In some embodiments, visualization engines may be arranged to employ rules, instructions, or the like, provided via configuration information to determine the available distributions or goodness of fit functions.

Note, this block is optional because in some embodiments the collected metric values may be assumed to be a normal distribution, or the like.

At block 1206, in one or more of the various embodiments, the visualization engine may be arranged to determine an upper percentile value based on the metric values and the distribution. In one or more of the various embodiments, visualization engines may be arranged to execute one or more functions to determine a value that may represent a upper percentile of the distribution of metrics values. In some embodiments, the upper percentile may be a constant, such as 0.9 (90%). In other embodiments, the upper percentile value may be computed based on the distribution of metric values. Also, in some embodiments, the determination of the upper percentile may vary depending on the type of metric being evaluated. Accordingly, in some embodiments, configuration information may be employed to associated upper percentile values or functions for computing upper percentile values with one or more metric types.

At block 1208, in one or more of the various embodiments, the visualization engine may be arranged to determine a lower percentile value based on the one or more metric values and the distribution. In some embodiments, similar to determining upper percentile values as described above, visualization engines may be arranged to determine a lower percentile value for the distribution of metric values.

At block 1210, in one or more of the various embodiments, the visualization engine may be arranged to generate one or more visualizations based on the upper percentile value and the lower percentile value. In one or more of the various embodiments, visualization engines may be arranged to generate a visualization of the distribution of metrics that includes the metric values in the upper percentile of the distribution of metrics and the metric value in the lower percentile of the distribution of metrics. In some embodiments, the remaining ‘middle’ values of the metric distribution may be omitted from the visualization. Accordingly, in some embodiments, the visualization may provide visual information associated with the outlier values of the metrics. Thus, in some embodiments, a user viewing the visualization may easily observe the outlier metric values without them being hidden or obscured by normal metric values.

Next, in one or more of the various embodiments, control may be returned to a calling process.

It will be understood that each block in each flowchart illustration, and combinations of blocks in each flowchart illustration, can be implemented by computer program instructions.

Further, in one or more embodiments (not shown in the figures), the logic in the illustrative flowcharts may be executed using an embedded logic hardware device instead of a CPU, such as, an Application Specific Integrated Circuit (ASIC), Field Programmable Gate Array (FPGA), Programmable Array Logic (PAL), or the like, or combination thereof.

In one or more embodiments, a microcontroller may be arranged to directly execute its own embedded logic to perform actions and access its own internal memory and its own external Input and Output Interfaces (e.g., hardware pins or wireless transceivers) to perform actions, such as System On a Chip (SOC), or the like.

Illustrative Use Case

FIGS. 13-20 illustrates a non-limiting examples of display panels that may be included user interfaces for managing distributed file systems in accordance with at least one of the various embodiments. One of ordinary skill in the art will appreciate that other display panels may be included in user interfaces without departing from the scope of the innovations described herein. Further, the below described display panels are sufficient of ordinary skill in the art to understand and practice the innovations described herein.

FIG. 13 illustrates a logical schematic of panel 1300 for showing capacity trends over time for distributed file systems in accordance with one or more of the various embodiments. In this example, panel 1300 includes a visualization the represents the capacity trends of a file system over a specified time window. In this example, for some embodiments, panel 1300 includes one or more user interface controls for modifying the time window. Further, in some embodiments, additional summary information may be included in the panel, the reports capacity information for one or more categories of data in the file system. In this example, the category summaries improve the ability of user to determine how much of the capacity may be allocated to administrative or operational use (e.g., snapshots, meta-data, or the like) as compared to user data.

FIG. 14 illustrates a logical schematic of panel 1400 for top directory changes for distributed file systems in accordance with one or more of the various embodiments. In this example, panel 1400 includes a shows one or more directories in a file system that have the highest capacity changes for a given time window. In some embodiments, visualization engines may be arranged to determine the number of top changed directories to show based on configuration information. In this example, for some embodiments, panel 1400 includes one or more user interface controls for modifying the time window.

FIG. 15 illustrates a logical schematic of panel 1500 for drilling down into the details of capacity change information for distributed file systems in accordance with one or more of the various embodiments. In this example, popup panel 1502 may be displayed as a user clicks or hovers over summary information displayed in the panel. In this example, popup panel 1502 shows a brief summary of the relevant changes for the time period. This may improve a user's immediate understanding of the context associated with the mark of interest. Also, in this example, in some embodiments, panel portion 1504 may be arranged to show expanded information that may be associated with the activity associated with the time window corresponding popup panel 1502. Accordingly, in some embodiments, users may simultaneously be provided context information and the supporting detail without having to navigate to another panel or user interface.

FIG. 16 illustrates a logical schematic of panel 1600 for file object count information for distributed file systems in accordance with one or more of the various embodiments. In this example, panel 1600 shows a current file count 1602 and directory count 1604 for a file system. Further, in some embodiments, rate-of-change information, such as, file count change 1606 and directory count change 1608, or the like, may be included for each file object type, providing additional context to the user. Accordingly, in some embodiments, while static count information may be of some value to a user trying to evaluate a file system, absent rate-of-change information, object count may be of limited utility. For example, in some embodiments, an object count that is high but unchanging may be little concerned compared to an object count that is high but increasing. Thus, in some embodiments, including current values and rate-of-change values in the same visualization may improve a user's ability to understand the state of the file system.

FIG. 17 illustrates a logical schematic of panel 1700 for displaying information about the most active clients in distributed file systems in accordance with one or more of the various embodiments. As described above, file system engines, monitoring engines, or the like, may be arranged to monitor various metrics associated with file system operations or file system clients. Accordingly, in some embodiments, visualization engines may be arranged to generate or display one or more panels, such as, panel 1700 the shows some or all of the monitored metrics. In this example, panel 1700 shows information about metrics associated with clients of a file system. In this example, section 1702 shows which clients have the most Input/Output operations per second. In this example, a network address and host name may be shown along with the values of the metric of interest. Similarly, in this example, section 1704 shows the information about the clients that have the highest throughput in in the file system. In some embodiments, additional or other metrics may be highlighted. In some case, visualization engine may be arranged to automatic rotated or cycle through information for more metrics than can fit on the panel at one time.

FIG. 18 illustrates a logical schematic of panel 1800 for the distribution of connections in distributed file systems in accordance with one or more of the various embodiments. In this example, panel 1800 may be arranged to show how the number of connections with a file system may be distributed or balanced across the individual nodes in distributed file system that may include multiple nodes. In this example, a comparison of mark 1802 to mark 1804 enables a user to observe that the connection count for node 1 is more than node 2. Further, in this example, legend 1806 includes color codes or patterns that may convey the type of communication or application protocols that may be associated with the connections. In this example, in the absence of a color illustration, it may be assumed that the legend color for NFS may correspond to the colors employed in this example, for mark 1802 and mark 1804.

FIG. 19 illustrates a logical schematic of panel 1900 for write throughput distribution in distributed file systems in accordance with one or more of the various embodiments. In this example, panel 1900 represents a compound visualization comprised of aggregate or average metric values for a time window and current value for the same metric. In this example, user interface 1902 may enable users to select a time window of interest, in this example, the time window is 24 hours. Also, in some embodiments, the vertical axis marks 1904 show how various write throughput values may be distributed. In this example, mark 1906 shows that the bulk write through rates in the time windows are between 0 MB/s and 2 MB/s. And, in this example, mark 1908 shows a current write throughput rate for the file system. Accordingly, in some embodiments, compound visualizations, such as shown in panel 1900, may improve a user's ability to gain insight into the operation of the file system by including aggregate/average metric values and current values in the same panel.
